The volume strings (e.g. ‘86% (-3.81dB)’) shown to the right of each
volume slider is now translatable/localisable. (The similar string
‘100% (0dB)’, centred *below* each slider, was already translatable.)
Also, the English strings now include a space between the decibel value
and the unit, e.g. ‘-3.81 dB’ instead of ‘-3.81dB’.
Fixes: https://gitlab.freedesktop.org/pulseaudio/pavucontrol/issues/52
Widgets (unlike Windows and Dialogs) returned by Gtk::Builder::get_widget*
start owned by the GtkBuilder object, the idea being that they will get
added to a container before the scope of the GtkBuilder object ends, and it
thus automatically gets destroyed.
But in the various ::create methods in pavucontrol, a pointer to the widget
gets returned, so that it can be added to a cointainer by the caller.
However as soon as the ::create method exits the GtkBuilder object owning
the widget, and thus also the widget gets destroyed, and we end up returning
free-ed memory.
This commit fixes this by making all ::create methods take a reference on
the widget before returning it, and having all the callers unreference the
widget after adding it to a container.

This allows us to set volumes up to ~153% aka +11dB.
Also show the current dB value in the UI - as pavucontrol is a bit more
developer-friendly than other volume UIs displaying this by default makes
sense.
